Fluid mechanics symbols and meanings
WebThe common symbols are j, J, q, Q, φ, or Φ (Greeklower or capital Phi), sometimes with subscript mto indicate mass is the flowing quantity. Mass flux can also refer to an alternate form of flux in Fick's lawthat includes the molecular mass, or in Darcy's lawthat includes the mass density.

WebMar 3, 2016 · A nice way to think about vector fields is to imagine the fluid flow they could represent. Specifically, for each point (x, y) (x,y) in two-dimensional space, imagine a particle sitting at (x, y) (x,y) flowing in the direction of the vector attached to that point, \vec {\textbf {v}} (x, y) v(x,y). Web2 days ago · So, Euler gave the equation of motion for incompressible and frictionless fluids as: ⇒. ∂ u ∂ t. + u. . u = -. P ρ. This equation could not explain the fluid dynamics of incompressible viscous fluids, thus Navier- stokes equation was derived with major correction by introducing viscosity term in the Euler equation: ⇒.
